Turboserif, I have the kind of plugs you are talking about. I had a hell of a time finding them. My car has an older engine than what it originally came with. I was told that Bosch does not make them anymore. I ended up paying $24 for each of the last Bosch plugs that an indie shop had. Later I found another brand of the same plug. I have had no problems with them. I have the 4 Bosch plugs for back-ups. I think I ordered them from Performance Automotive. Check with them. I don't have the number with me right now, I can get it if you can't find it. andy
